SPECIFICATION forming part of Letters Patent No. 320,382, dated June 16, 1885.

Application tiled September 23, 1884.

T @ZZ whom, it may concern:

Be it known that I, REUBEN MUNRO, a citizen of the United Sta-tes, residing in the city and county of San Francisco, and State ofCalifornia, have invented certain new and useful i Improvements in Journal- Lubricators for y Railway-Axles; and I do hereby declare that the following is a full, clear, and exact dej seription of my said invention and of the manner in which I proceed to construct, produce, and apply the same, reference being had to the drawings that accompany and form part of this specitication.

My invention relates to alubricatingdevice for railway-axles; and it consists in certain usual construction of parts and their application and comb nation within a car-axle box, producing a lubricant of improved operation and great simplicity, cheapness of manufacture, and durability.

In the accompanying drawings, referred to l by figures and letters, Figure lis a longitudinal section taken vertically through an axle-box and the parts of my device applied to it. Fig. vertical, taken trans versely. Fig. 3 is a detail view.

The axle-box B is of any construction now in use wherein the space or chamber below the journal is of sufficient size to admit the parts of my device. These parts consist of a tray or plate, A, with a perforated surface set on spring-legs beneath the journal and a body of some absorbing material or substanceas cotton-waste or sponge-which, being laid upon the plate or yielding' surface, is held up lagainst the under .surface of the journal. j The plate A has a number of holes or perforations, a a., through which the oil or lubricant contained in the lower part ofthe axle-box chamber reaches the absorbent material C, and the edges of the plate are turned up around the four sides to form a rim for eonfin- The spring-legs d d are ing this material. tlat plate or leaf springs.

The improved construction is to take two metal springs and fix them by one end to the opposite sides of the tray or plate in such manner that they can be bent under the tray and from opposite directions to cross or extend past each other underneath the middle of This number could be increased, if l the tray.

necessary, by adding one or two spring-legs i (No model.)

. in the same manner. The bottom of the axlebox B is provided with ledges or projections b b, lying on each side of the springs rl d, as shown in Fig. l, and serving to keep the springs d d, with their attached plate A, under the spindle. Upon this spring-supported surface I place a body of some soft absorbent material or substance as the vehicle for applying the oil or lubricant. Tow, cotton, or prepared sponge will answer for this purpose. A body of it is laid on the tray in l suflicient quantity to cover the length of the l journal, and insuch mass or body as will iill i up the space above the tray and attbrd required contact with the journal. Vhile thus supplied and held to the place this material is constantly receiving and taking up a supply from the lubricant in the chamber beneath it through the splash and disturbance of the liquid, while it is not submerged or immersed, but is held up out of thel liquid. The condition of the lubricant and the quantity on hand in the chamber can be ascertained, therefore, at l any time by raising the lid or cover of the box, and thus the liquid can be replenished when needed without waste or extravagant use. rlhe construction likewise affords a ready and inexpensive renewing of the lubricating medium when required.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination, with the car-axle, absorbent material C, and perforated plate A, of the springs d d, formed of strap-pieces secured at the ends of the plate A and bent into an inclined position, as shown, so that the springs from the two ends of the plate cross each other and rest upon the box under the opposite ends of said plate.

2. The combination, with the car-axle, absorbent material C, plate A, and springs d d, of the box B, having the ledges or projections b Z) 011 the bottom thereof, as and for the purl pose set forth.

In witness that I claim the foregoing I have hereunto set my hand and seal.

REUBEN MUN RO.
